Material Description
Anionic cellulose powder prepared by etherification modification of natural cellulose, with molecules containing sodium carboxylate active groups. Prioritize the use of protective gel to reduce filtration loss, minimize viscosity increase, optimize mud cake quality, and stabilize the water-based drilling fluid colloid system.
Core selling point
1. Excellent filtration reduction effect, with thin, dense and smooth mud cake
2. Low viscosity, will not cause excessive increase in drilling fluid viscosity and shear
3. It has salt and calcium resistance and is suitable for freshwater and saltwater drilling fluids
4. Strong adhesive protection ability, maintaining the stability of mud colloids
5. Excellent compatibility, can be used in combination with various water-based drilling fluid treatment agents
6. Easy to disperse and dissolve on site, suitable for high-density drilling fluid systems
Product Advantages
-Effectively control the filtration loss of drilling fluid, reduce the invasion of filtrate into the formation, and assist in protecting the wellbore
-Low viscosity increase, used in high-density drilling fluids, will not cause mud to become too thick, and rheological properties are easy to control
-Resistant to salt and calcium ion pollution, both shallow, medium, and deep well saltwater drilling fluids can be used stably
-Good protective effect, inhibits clay particle agglomeration, and ensures stable performance of drilling fluid system
-Good powder dispersion, less prone to clumping during feeding, and simple on-site mud mixing and maintenance
Usage
1. It can be used alone or in combination with other water-based drilling fluid treatment agents.
2. Prepare high-density drilling fluid or add it in sections when it is necessary to control filtration and strict control of sticking and cutting.
3. It is recommended to refer to the working conditions for the recommended dosage on site. It is suggested to conduct indoor trials to determine the optimal dosage before on-site deployment.
4. Normal circulation stirring, sufficient dissolution and dispersion can be used for drilling operations.
Storage precautions
Sealed and moisture-proof, avoiding exposure to sunlight and rain; Use up as soon as possible after opening; Wear dust-proof protective equipment during operation.
